G. w. MOSEY ET AL VALVE TAPPET SILENCER Filed May 10, 1921iifiimamiiiiLE are anchored on seated at one end in seats (15) in theback of the compartments of the cages and in the ends thereof. Theopposite ends of the springs abut against the inside edge of the blockswith notches in the blocks receiving the same.

The influence of these springs will press the blocks outwardly and holdthem in contact with the guide plates. To limit the action of thesprings, pins (16) are carried by the cages with slits (17) in theblocks in which the pins are received.

From the above it will be seen that the tappets and their associatedparts are under constant influence of the blocks (7) which will overcomethe customary noisy operation of this part of the engine. The blocks actnot only to steady the tappets and the push rods at their contactingends but they also act in the capacity of an absorbing or cushioningmedium for vibration and a noise deadener- The details of constructionreferred to in the drawing and throughout the specification should beconsidered only as an example of one way the invention may be reduced topractice, as certain changes may be required to adapt the arrangement tovarious types of engine constructions.

We claim:

1. A valve tappet silencing device for in ternal combustion enginescomprising means mounted behind the valve tappets in con stant contacttherewith and spring means for maintaining said contact.

2. A valve tappet silencing device for internal combustion enginescomprising a block mounted behind the valve tappets in constant contacttherewith and spring means for maintaining said contact.

3. A valve tappet silencing device for internal combustion enginescomprising a block mounted behind the valve tappets in constant contacttherewith and spring means for maintaining said contact, said block andspring means being confined within a cage which in turn is rigidly fixedto the engine casting. i

4. A valve tappet silencing device for internal combustion enginescomprising a block mounted behind each two of the valve tappets and incontact therewith, a confining cage divided to form a separatecompartment for each of a pair of blocks and spring means in eachcompartment of the confining cages for maintaining a constantcontact oithe blocks with the valve tappets.

5. A valvetappet silencing device for internal combustion enginescomprising a block mounted behind each two of the valve tappets and incontact therewith, a confining cage divided to form a separate compart:ment for each of a pair of blocks and spring means in each compartmentof the confining cages for maintaining a constant contact of the blockswith the valve tappets, said confining cages being rigidly fixed to theengine casting and including means for limiting the influence of thespring means relative to the blocks.

6. A valve tappet silencing device for internal combustion enginescomprising an oblong fibre block mounted behind each two of the valvetappets and in contact there with, each of the blocks having notches cutin one of their plane surfaces to partly encircle the valve tappets, aconfining cage for each two of the blocks, said cages including aseparate compartment for each block, springs 'inosaid compartmentsbehind said blocks adapted'to maintain the blocks in constant contactwith the valve tappets, and means for restricting the influence of saidsprings.
